SPARKLING CAT 158-6634 Switch – Reliable Excavator Electrical Part

The Caterpillar Switch GP-Toggle (Part No. CA1586634 / 158-6634 / 1586634) is a genuine OEM electrical component used in various CAT track loaders and excavators, including models 963D, 973D, 953D, 330D MH, and 325D.

Manufactured from high-quality polyamide plastic, this toggle switch is engineered to provide durable performance, electrical reliability, and resistance to heat, wear, and vibration — all critical for heavy-duty applications. It plays a key role in controlling specific machine functions from the operator cab, offering responsive switching and long operational life.

This part is an ideal replacement for worn or faulty switches in your Caterpillar equipment. Its precise fit and OEM-grade construction ensure hassle-free installation and consistent performance in demanding jobsite conditions.

   SPARKLING MACHINERY NEW 6675-31-1011 Crankshaft is a critical power transmission component tailor-made for compatible heavy-duty diesel engines used in excavators, loaders, and industrial machinery. As the "rotational core" of the engine, it converts the reciprocating motion of pistons into continuous rotational torque, which drives the machinery’s hydraulic systems, undercarriage, and working mechanisms. This function is essential for delivering consistent power to support heavy-duty tasks like deep digging, large-volume material lifting, and continuous mining operations.

   Designed to meet original equipment performance standards, it maintains stable operation even under extreme conditions—including high rotational speeds, intense mechanical loads, and temperature fluctuations. It ensures smooth torque transfer with minimal vibration, preventing premature wear of engine components and safeguarding long-term operational efficiency. Backed by strict performance verification, it guarantees reliable power output to minimize engine downtime and keep heavy machinery running continuously.

 SPARKLING MACHINERY NEW 416F 420F 422F 428F 3435643 343-5643 Air Cleaner is a dedicated air filtration component exclusively designed for 416F, 420F, 422F, and 428F construction machinery (such as backhoes and loaders). As a core part of the machinery’s engine protection system, it efficiently filters dust, debris, and other contaminants from incoming air before it enters the engine combustion chamber. This function is critical for preventing abrasive particles from damaging engine components (e.g., pistons, cylinders, and valves) during heavy-duty operations like excavation, material handling, and site grading—directly preserving engine performance, extending service life, and reducing maintenance frequency.

   Engineered to match original equipment performance standards, it maintains high filtration efficiency (over 99.5% for particles ≥3μm) even under harsh working conditions, including dusty construction sites, gravel yards, and agricultural fields. It resists clogging and air flow restriction, avoiding engine power loss or overheating caused by insufficient air supply. Backed by strict performance verification, it guarantees reliable air purification to support uninterrupted operation of 416F/420F/422F/428F machinery.

The A/C Compressor (part no. 400102‑00381A / K1057338) is a reliable 24 V Denso 10PA15C air conditioning compressor designed to restore cabin comfort in Doosan (Daewoo) DX225 and DX340LC excavators. Featuring an 8-groove (8PK) clutch pulley (Ø 145 mm), it delivers smooth, efficient operation under heavy-duty use. Built to exceed OEM specifications and shipped globally, this compressor is available in brand-new aftermarket versions with options of 1‑year warranty and prompt delivery.
